. 1915. Serial No. 53,904.

To all whom it may concern:

Be it known that I, ALVAJ. FISHER, -a

citizen of the United States, residing at' Evanston, Cook county, Illinois, have invented certain new and useful Improvements in Ironing-Machines, of which the fol lowing is a specification this application being divisional of an application filed by me on October 15, 1914, Serial No. 866,773.

My invention relates to ironing machines of that type in which a heated shoe cooperates with a padded roll in the ironing operation. One of the principal objects of my invention is to provide a novel and eflicient construction of such shoe whereby the ironing surface thereof shall be properly and uniformly heated. My invention involves other and advantageous features of con struction which will beapparent from the description hereinaftergiven.

In the drawings Figure 1 is a side elevation of my machine; Fig. 2 an'elevation of one end thereof; Fig. 3 a vertical cross section of the shoe andFig. 4a detail section of a portion of the operating mechanism for V the shoe.

.The same figures of reference are used as so far as the sameare applicable.

' Referring to the embodiment of my invention as herein shown, the machine is provided with a supporting frame composed vof end frames 1 and the tie-rods 2 connected therewith. Upon the tops .of these end frames are supported the bearing brackets 3 for the horizontal driving shaft 4 of the padded roll 5. In so far as my present invention is concerned the drivin mechanism for rotating the shaft may be of any desired character. In the present instance the prime mover is an electric motor 6 supported by one of the end frames and adapted to com- :municate'its power from the pulley 7 and belt 8 through suitable driving connections (not shown) to said shaft 4.

Referring to the shoe, the same comprises an arc-shaped hollow body 24 extending longitudinallyof the roll and having itsironing surfaces corresponding substantially to the are or curvature of the roll. At pre' determined distances apart there are formed interior of the shoe a series of vertical ribs or flanges 25 projecting outwardly, that is away from the roll, and ha ing the fun ,flanges were omitted.

at 31 to the lower corner ofthe shoe body of the shoe and along its upper edge to the outwardly extending flange 28 into i which the top edges of the flanges 25 merge. The casing 26 is provided with air inlet openings 26 andthe flange 28 with outlet openings 28. i

In the present'instance, the burner is a gas burner including the series of slits 29*, thereby forminga burner. This burner is arranged-at the lower point of the are or crescent-shaped space formed by the body of the shoe and the casing 26,

as seen in Fig. 3, in which position it is closev to thelower portion of such body anddi rectly below the vertical ribs or flanges 25.

gas pipe 29 having 'a I One of the main objects of. this invention is to provide for the proper and uniform heating of the shoe, that is, the ironing surface thereof and this construction acc0m-- plishes this purpose. The flame is at all times directed toward and upon the body 24 v and upon the flanges 25, and to insure this action the outlet holes-28 are located as sl1own,jthat is, at extreme upper point ofs-uch crescent. Moreover, by the provision of the flanges 25 the heat is conducted thereby inwardly to the shoe body and also distributed more uniformly over the surface of such body than would be possible if such As shown in Fig. .3 and by preference, the ironin surface is not the metal surface of the bod steel and therefore corrodible, but is made of a sheet of non-corrodible material 30, such as German silver 'or'the like. This sheet is secured along its longitudinal while its upper portion {is reversely bent over the top projecting edge of the shoe y 24, which is usually made of body and secured thereto in suitable manner at 32. The -parts32 also hold a stri 30 (which might be integral with'sheet 30 that extends along the'body and is turned upwardly to act as a deflector cooperating with the outlet holes 28;, that the heated air and the Products of comwith the result bustion are deflected away from the operator.

39 whose inner end passes through a The shoe body is provided at its opposite ends with depending arms 33 whereby the shoe is supported and capable of a swinging movement toward and away from the roll. The lower ends of the arms 33 are pivoted upon thestuds 33? on the inner sides of the bearing brackets 3,'Fi s. 1 and 4. A rod or rock shaft-34 exten s longitudinally of the machine between these brackets and is provided with a handle 35 connected therewith for the purpose of rocking the shaft by hand. Operating connec tions are provided at-opposite ends of the rock shaft and the arms 33 and as these connections are similar a description of one of them will apply to both. One of the connections is shown in detail in Fig. 4. An upwardly extending arm 36 is secured to the rock shaft 34 and pivotally connected by means of the pin or stud 37 thereon to a block 38 having a rearwardly extend'in roi 40 pivotally connected by means of the stud 41 to one of the arms 33 of the shoe.

When the handle 35 is thrown up in the position shown in Fig. 2, the shoe is in ironingposition and the proper tension is afforded by the springs 42 interposed between the blocks 38 and 40. Means for stopping the handle 35 and its oscillating parts in both extreme positions, are provided at each end of the machine comprising collars 43 is down.

' throw of the handle may be regulated.

I claim:

1.-In an ironing machine, the combina tion, with a roll, of a hollow shoe having a body corresponding substantially with the curvature of the roll, and having outlets at its upper portion, means for heating the shoe, and a sheet of non-corrodible material afiixed to said body 'to'form the ironing surface thereof, one end of the sheet being arranged above said outlets to act as a deflector.

2. In an ironing machine, the combination of a roll, a hollow heated shoe cooper-, ating therewith having a contact face ar ranged to span-a rear arc of the roll and pivoted at its lower portion in front of its center of gravity to tend easily to fall away from the roll, an operating handle pivoted in rear of said roll, a horizontal rock shaft operated by said handle, an upwardly extending crank arm on said, rock shaft, a horizontally extending rod pivotally connected at opposite ends, respectively, to said crank arm'and to a point on the shoe intermediate the pivotal axis of said shoe and its contact area, one of said pivotal connections for said rod involving a bearing wherein the rod may slide axially, and spring means for resisting such sliding action of said rod.

'3. In an ironing machine, the combination of a roll, a hollow heated shoe cooperating therewith pivoted at its lower portion, a handle and yielding connections between the handle and shoe for holding the latter in operating position with a yielding pressure, comprising a rock shaft to which the handle is connected, a'crank arm thereon, and-a spring pressed rod pivotally connected withthe crank arm and the shoe, and also adjustable means for limiting both extreme movements of the handle and its said 0011- nections.

4. In an ironing machine, the combination of a roll, a hollow heated shoe in rear of said. roll coiiperating therewith and pivoted at its lower portion, an operating handle pivoted in rear of said shoe, yielding connections between said handle and. said i ALVA J. FISHER.
